IMPROVEMENT IN PREPARING CEREALS FoR Fooo.

Specification forming part of Letters Patent No. 173,211, dated February a, 1876; application filed November 12, 1875.

To all whom it may concern.-

Be it known that I, Lewis S. OHIoHEs'rEa, of the city and State of New York, have invented an Improvement in Preparing'Cereals for Food, of which the following is a specificable to cook the ground or crushed grain in a quiescent conditiojn,and then dry the .same by heat in a separate vessel while agitated, in order that the aqueous matters may be more thoroughly removed after the cereal is in an otherwise completely-prepared condition. In the drawing, Figure 1 is a vertical section of the apparatus for cooking the cereal.

Fig. 2 is a longitudinal, and Fig. 3 a transverse section, of the apparatus for drying and cooling the cooked material.

The vessel a is made with trunnions b b, one or both of which are hollow, and receive steam-pipes and couplings. These trunnions are supported by a suitable frame, 0, and there is a discharge-pipe, d, and valve for the delivery of the water of condensation. The inner vessel fis connected at its edges to the vessel a, and there is a cover, g, with a pipe, k, that is preferably connected to an exhaustblower, whereby vapors from the vessel f will be drawn off, and there is a perforated platform, 70, in this vessel f, and an opening and valve, 1, to the conical bottom of said vessel f.

I proceed to prepare the wheat or other cereals, or mixture of difl'erent cereals, by grinding. or cracking the same into pieces of thedesired fineness, and these are placed in the vessel f, and steam is admitted by the valve l, and passes up through the perforated bottom k, and through the cereals, and the moist.

ure of the steam and the heat cook the same sufliciently to adapt the mass tothe subsequent operations. When the mass has been subjected to the direct action of the steam passing through the same for the required period the valve 1 is closed, and the heat continued by the steam acting around the vessel f, and within the jacket or vessel a, and when the cooking operation is completed the cover 9 is removed, and the mass turned out into a suitable vessel, by partially revolving the apparatus upon the trunnions b b.

The object in shutting 011' the steam from passing continuously through the cereal is to cereals have been introduced, and warm or 7 hot air is admitted or forced. in. at n, and exhausted or allowed to escape by the trunnion n The air passes into and heats the drum 8, and returns through the perforated head It; thence through the grain, and out through the perforated head t, and escapes by n. In its passage the moisture of the agitated cereals is removed, and after the same is dry the mass may be cooled by the admission of atmosphere at ordinary temperature, and then the flap o is opened and the cereals removed, after which it may be put up in suitable packages for sale. j I

The cereals thus prepared are so thoroughly cooked that they may be used for food by soaking in water or boiling for a very short time; but usually they Willbe prepared in the form of gruel or mush by simply stirring the same into boiling water.

v I claim as my invention 1. The vessel f, having a perforated platform, It, and steam-inlet valve 1, in com bination with the surrounding vessel a, forming a steam-jacket, and the supporting-trunnions b b, as and for the purposes set forth.

2. The drying-vessel composed of the cylinder m, sustained upon hollow trunnion's, and
